Debro Siddiq Abdul-Akbar seeks to appeal the district court’s order dismissing his complaint without prejudice. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2000), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2000); Fed.R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order Abdul-Akbar seeks to appeal is neither a final order nor an appealable interlocutory or collateral order. See Domino Sugar Corp. v. Sugar Workers Local Union 392, 10 F.3d 1064, 1066 (4th Cir. 1993). Accordingly, we deny his motion for appointment of counsel and dismiss the appeal for lack of jurisdie*296tion. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
